Randy, If you remove all 4 baffels (which sounds greeeat) make sure you leave the reducer, that is in the front of the pipes, in. You need that for backpressure.
4 baffels out is not rediculously loud either. It gets a good amount of volume when you W.O.T. But just casually using the throttle won't blow the neighbors out of bed. F.W.I.W.
